So if I understand correctly, with this commit I don't need to downgrade my bullet M to v.5.5.10 (U-Boot 1.1.4.2-s594 (Dec 5 2012 - 15:23:07)) and I can just downgrade to v.5.6.x (U-Boot 1.1.4.2-s956 (Jun 10 2015 - 10:54:50)) and maybe even the firsts 6.0.X (without the signed image) mtdparts differences between the 2 uboot version: https://community.ubnt.com/t5/airOS-SDK-Custom-Development/5-6-2-TFTP-ERROR/m-p/1310208/highlight/true#M2354 Thanks Etienne > > Reported-by: Andreas Ziegler <d...@andreas-ziegler.de> > Signed-off-by: Matthias Schiffer <mschif...@universe-factory.net> > --- > target/linux/ar71xx/image/ubnt.mk | 1 + > 1 file changed, 1 insertion(+) > > diff --git a/target/linux/ar71xx/image/ubnt.mk > b/target/linux/ar71xx/image/ubnt.mk > index 65ed708..899d5d0 100644 > --- a/target/linux/ar71xx/image/ubnt.mk > +++ b/target/linux/ar71xx/image/ubnt.mk > @@ -47,6 +47,7 @@ define Device/ubnt-xm > UBNT_TYPE := XM > UBNT_BOARD := XM > UBNT_CHIP := ar7240 > + KERNEL := kernel-bin | patch-cmdline | relocate-kernel | lzma | uImage lzma > IMAGES := sysupgrade.bin factory.bin > IMAGE/factory.bin = $$(IMAGE/sysupgrade.bin) | mkubntimage-split > IMAGE/sysupgrade.bin = append-kernel | pad-to $$$$(BLOCKSIZE) | > append-rootfs | pad-rootfs | check-size $$$$(IMAGE_SIZE) > > _______________________________________________ > lede-commits mailing list > lede-comm...@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/lede-commits _______________________________________________ Lede-dev mailing list Lede-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/lede-dev
